User manual BIAMP MEQ301-MEQ152

[. . . ] The mEQ152 provides two independent channels of true 2/3-octave frequency control. The mEQ301 provides a single channel of true 1/3-octave frequency control. The use of Constant-Q technology guarantees precise room tuning with less filter interaction, better filter combining, and constant filter bandwidth at any setting. [. . . ] However, this may be an indication that the equalizer requires service. Outputs: These plug-in barrier strip connectors provide balanced output from the respective channels. For unbalanced output, connect to the Outputs with high to (+) and ground to ( ), leaving (-) unconnected. Inputs: These plug-in barrier strip connectors provide balanced input to the respective channels. For unbalanced input, connect to the Inputs with high to (+) and ground to both (-) & ( ). 2 mEQ301 FEATURES FRONT PANEL 25 boost 31. 5 40 50 63 80 100 125 160 200 250 315 400 500 630 800 1K 1. 25K 1. 6K 2K 2. 5K 3. 15K 4K 5K 6. 3K 8K 10K 12. 5K 16K 20K boost 0 gain +12 0 -12 12dB peak on 6dB out EQ in mEQ301 cut cut Filter Controls: These 30 slide controls adjust the gain in each of the filter bands (25Hz~20kHz). Each control has a range of ±12dB or ±6dB boost/cut depending upon the position of the Range Switch. Master Gain Control: This slide control adjusts the overall gain of the equalizer only when the EQ Bypass Switch is depressed (in). Use this control to compensate for changes in gain due to filter adjustments. Range Swich (12dB / 6dB): This switch selects the boost/cut range of the filter slide controls. When depressed (in), this switch selects the 6dB range. Peak Indicator: This red LED indicates signal levels of at least +15dBu (9dB below clipping) are present in the equalizer. EQ Bypass Switch (In / Out): This switch activates or bypasses the Filter Controls and Master Gain Control for the equalizer. Use EQ Bypass to compare equalized signals to un-equalized signals. REAR PANEL 27V 50/60 Hz ~ BIAMP SYSTEMS PORTLAND, OREGON output input an affiliate of Rauland-Borg Corp 15 watts class 2 wiring MADE IN U. S. A. AC Power Cord: The external power transformer provides 27 Volts AC to the equalizer, and is detachable via a 5-pin DIN connector. The equalizer has two internal `self-resetting' fuses (there are no user servicable parts inside the unit). If the internal fuses blow, they will attempt to re-set after a short period. However, this may be an indication that the equalizer requires service. Output: This plug-in barrier strip connector provides balanced output from the equalizer. For unbalanced output, connect to the Output with high to (+) and ground to ( ), leaving (-) unconnected. Input: This plug-in barrier strip connector provides balanced input to the equalizer. For unbalanced input, connect to the Input with high to (+) and ground to both (-) & ( ). 3 SPECIFICATIONS mEQ152 Frequency Response (20Hz-20kHz @ +4dBu): Total Harmonic Distortion (20Hz-20kHz @ +4dBu): Intermodulation Distortion (SMPTE): Noise Floor (20Hz-20kHz @ unity gain w/ filters flat): Maximum Input Level: Input Impedance (balanced): Maximum Output (600 ohm load): Output Impedance (balanced): Power Consumption: Power Requirements: Dimensions: Height (1 rack space) Width Depth Weight: 1. 75" (44mm) 19" (483mm) 7. 25" (184mm) 6 lbs.
